Greg Davies and Alex Horne welcome five fresh competitors, including Guz Khan, who are desperate to lay their mitts on Greg's golden head-trophy. This time: creepers, catapults and one (fake) cactus.

The contestants have a mountain to climb, but can they hack teamwork? Morgana Robinson inspects suspect doggy bags. Guz Khan slaps a space hopper.

Taskmaster Greg Davies struggles to contain his scorn as Desiree Burch does something inexplicable with sand, Victoria Coren Mitchell draws an exploding cat and Alan Davies hurts himself with a rubber band.

In this edition Morgana drenches herself in peas, Victoria learns a new skill, Desiree makes a political statement with jam, Alan piles on the sunglasses and Guz pens a new song

In the 100th episode, Victoria celebrates with a flapjack, Morgana celebrates by slicing up some plastic balls, and Guz celebrates by barricading himself in the Taskmaster house.

This week, Desiree attempts to affix tennis balls to gaffer tape, Victoria tries to construct a rudimentary pulley system, while Alan finds out how many circles he can carry.

Guz Khan currently holds a slender lead in this series, but with four episodes to go, any one of our five famed comics could easily walk off with Greg Davies's gorgeous golden head tucked under their arm. This time, Alex Horne lends his considerable acting skills to a promotional film, while Morgana Robinson passes a pole through a sponge, and Victoria Coren Mitchell tries to come to terms with a swanee whistle.

Desiree Burch draws on her face, Guz Khan endures a ball to the groin and Alan Davies loses an eye, as the quest to win Greg Davies' golden head heats up among our comic contenders

Scores are tight in the penultimate episode of the series. Can Alex Horne give Desiree Burch goosebumps? Plus: paint throwing, and enforced yawning.

In the prestigious grand final, there's chocolate gobbling, bizarre body movements and indecent proposals, but which plucky competitor will be declared the Taskmaster series champion?
